A significant number of firms, from small businesses to multinational corporations, incorporate online advertising into their marketing strategy. Online advertisements typically involve at least two separate firms: the advertiser or agency which purchases or sponsors the advertisement and the publisher or network which distributes the ad for display. Because of the close relationship between technical innovation and online advertising, many firms specialize in both. For example, most search engines couple their search service with an advertising program, exploiting the benefits of keyword-based search technology by including ads in search results.

Let’s look closer on the most popular online advertising form as traditional banner. PPC advertising form will be explained in details in 8 lessons of our next Step.A Web banner or banner ad is a widely used form of advertising on the Internet. This kind of online advertising entails embedding an advertisement into a Web page. It is intended to attract traffic to a website by linking them to the advertiser’s website.

Generally the advertisement is constructed from an image (GIF, JPEG, PNG), JavaScript program or multimedia object employing technologies such as Java, Shockwave or Flash, and often employing animation or sound to maximize presence. Images are usually in a high-aspect ratio shape. Banners are usually placed on Web pages that have interesting content, such as a newspaper article or an opinion piece.

The Web banner is displayed when a Web page that references the banner is loaded into a Web browser. This event is known as an “impression“. When the viewer clicks on the banner, the viewer is directed to the website advertised in the banner. This event is known as a “click-through”. Many banner ads work on a click-through payback system.

At the base of a click-through system are mathematical calculations of the number of users (users clicking on an ad) divided by impression number. We remember that the term impression means the number of times the ad was delivered. For example, if your banner ad was delivered 100 times (impressions delivered) and 1 person clicked on it (clicks recorded), then the resulting CTR would be 1%.

It should be noted that banner ad click-through rates have fallen over time, often measuring significantly less than 1% and choice of an appropriate advertising site with high affinity is very important crucial factor in this situation. Personalized ads, unusual formats, and more obtrusive ads typically have higher click-through rates than standard banner ads.

When the advertiser scans their log files and detects that a Web user has visited the advertiser’s site from the content site by clicking on the banner ad, the advertiser sends the content provider a small amount of money (usually around five to ten US cents). This payback system is often how the content provider is able to pay for the Internet access to supply the content in the first place.
